Unseen magic

Fin lives in the magic-infused town of Aldermere, the only place she's ever felt safe from her overwhelming fears. A simple cup of tea from the tea shop makes them disappear, and all it costs is a single memory. But when a visit to the tea shop goes sideways, Fin unleashes a shadow self who wreaks havoc everywhere she goes. It's up to Fin, her cousin Eddie, and her friend Cedar put things right before the monster destroys Aldermere.
